No, this is not possible. Please note that DisplayPort to HDMI cables (as with most cables involving protocol/signal conversion) are not bidirectional adapters, which means they only work in one direction -- from a DisplayPort output to a HDMI input. 

Connecting these type of cables backwards will not allow an HDMI output port (such as those on a dock) to function with a DisplayPort input on a monitor.

Most Windows notebook computers power management settings will default to putting the computer to sleep with the lid closed, regardless of any external displays, keyboard, or mouse connected to the computer. If this is happening but you would prefer the system to remain active with the lid closed utilizing the external display or displays, these settings can be changed by performing the following:

For Windows 10:

1. Start by right-clicking on the Start button and select Power Options from the menu.
2. From the right side of the Power Options settings page, select the blue link for Additional power settings

   

3. From the choices present on the left-hand side of the Power Options window, please click on Choose what closing the lid does
4. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

5. Click the Save Changes button and restart the system (making sure that the laptop’s power adapter is also connected) and test the behavior again.

For Windows 11:

1. Start by right-clicking on the Start button and select Power Options from the menu.

   

2. In the upper left corner of the settings window, in the search box, type "lid" then select Change what closing the lid does from the search results

   

3. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

4. Click the Save Changes button to apply the new settings.

Closing the lid should no longer put the computer into sleep mode when an external display and power source is connected, instead one of the external displays should now become the Primary display with the desktop icons instead of the laptop's built-in display.

The lid may still need to be opened to perform the following tasks:

• To power on the computer from a fully powered off state
• To log into the computer if logged out or if the computer is restarted with the lid closed
• To wake the computer from a deep sleep state ( hibernation, or Windows hybrid sleep states )

If your Windows laptop will not boot properly when a docking station is connected to the laptop, most often the cause is an external device connected to the docking station (for example an external USB storage drive) as opposed to the dock itself. 

If you are affected by this condition, please follow these steps in order to isolate the behavior further:

1. Disconnect all USB devices from the docking station and put them aside for the moment.
2. Disconnect any displays connected to the dock's video outputs.
3. Disconnect any audio devices connected to the dock's audio ports (if present).
4. Disconnect the Ethernet network cable from the dock's Ethernet port (if present).
5. The only remaining connections should be the dock's power adapter cable and the USB cable used to connect it to the laptop. No other external devices should be connected to the dock.
6. While in this state, reboot the laptop to test the behavior.
7. Assuming the laptop boots as expected, please reconnect each device back to the dock one at a time and reboot after each one to test the behavior again. Please reconnect the displays first, then the audio devices, then the Ethernet cable. Please reconnect any USB devices to the dock last, again rebooting after each one is added to test the behavior.

In our experience helping others, the most common cause of this behavior is an external USB storage drive connected to one of the dock's USB ports.  In some cases, a laptop may try to boot from an external storage drive by mistake as opposed to the laptop's built-in storage drive.  Since most external USB storage drives are not 'bootable', this can interrupt the boot process. 

If this behavior occurs, the most common way to mitigate the behavior is to access the laptop's System BIOS (also known as UEFI firmware) to change the 'boot order' settings to ensure that the laptop's internal storage drive is the first boot option.  Doing so helps ensure that the laptop will not try to boot from an external USB storage device. 

Every laptop system is different, so the best resource for accessing the System BIOS and changing the settings is the manual for the laptop provided by the laptop manufacturer.   

There are various reasons and configurations that can benefit from having more than one network adapter present on a PC.

For users with newer networking products, featuring 2.5Gbps link rates or greater, it may be beneficial to prioritize that network connection over others on your PC that are still connected to your network/LAN.

Below is a list of pre-tested power adapters and corresponding power prongs/cables for Plugable docking stations that can be purchased on eBay if a replacement is needed.

If the power adapter for your docking station or region is not listed or if it out of stock on eBay please contact us at support@plugable.com and we will be happy to assist further.

We offer a 30-day return period for our replacement power adapters listed on eBay.

If your package is missing one or more of the items that should be included with your Plugable dock (included items are listed on a chart on the side of the box), start by double checking if the part is still in the packaging. Pieces can occasionally get stuck in the corners under the main insert in the box.

If you are still unable to locate the piece, please contact support@plugable.com with the following information:

1.  Amazon Order ID (or other proof of purchase) associated with your Plugable device.

2. A description of the parts that are missing from your order.

3. Your preferred shipping address (and a phone number associated with that address).

4. The serial number of your Plugable Dock.

Most Plugable docks do not officially support monitors over 60Hz including 120Hz or 144Hz refresh rate unless otherwise specified on the Plugable product page or listing. 

DisplayLink USB Graphics technology and Silicon Motion based docking stations and graphics adapters, like our USB 3.0 dual display and USB Type-C triple display docking stations, are limited to 60Hz fresh rate by the USB graphics controller hardware.

USB Type-C DisplayPort Alternate Mode docking station and ports on our USB Type-C Triple Display Docking Stations can support higher refresh rates, but may be limited by the computer's capability and available bandwidth to the docking station.  Additionally, when paired with DisplayLink or Silicon Motion USB graphics, having displays at different refresh rates may reduce overall system performance.  Due to this we normally recommend limiting all connected displays to 60Hz refresh rate when using DisplayLink and Silicon Motion graphics technology with directly connected, or USB Type-C DisplayPort Alternate Mode controlled displays.

Monitors with refresh rates higher then 60Hz may be connected to a docking station operating at up to 60Hz, or connected directly on the computer's HDMI or DisplayPort to ensure the display is powered by the system's native GPU.

Unfortunately Plugable products do not support the Apple SuperDrive.

The Apple SuperDrive has stringent power requirements that can only be met by directly connecting the SuperDrive to your host laptop. As a result at this time Apple recommends only using their USB-C adapter cables. You can find more information on that here -→ How to connect the Apple USB SuperDrive

We are often asked if it is okay to leave a notebook computer connected to one of our USB-C docking stations with Power Delivery for extended periods of time.  The short answer is yes, it is no different from leaving the laptop connected to the manufacturer's original USB-C power supply for the same time.  The long answer is yes for modern laptops, and maybe for older (1990s-early 2000s laptops) and involves going into the different battery technologies used in consumer electronics devices.

Another common question is if it is possible to use the docking station but to disable powering and charging the computer.  When a modern notebook computer runs on battery power it will often set the system to a reduced power state which may impact performance, or connected devices and we recommend always powering the computer when using a desktop docking station.  For all of our docking stations that provide power to the host computer this will not affect the lifespan of the computer's battery.

Modern Laptop Batteries: Lithium-Ion

Lithium-ion (li-ion) batteries are found in a wide range of consumer electronics from notebook computers and cell phones, to electric cars, power tools, and wearable electronics like wireless earbuds.  Li-ion offers fast charging, high-current discharging, fairly long service live compared to other rechargeable battery technologies and are relatively inexpensive.

The life-span of a rechargeable battery depends on many factors including age, temperature history, charging patterns, the chemical composition of the specific battery, and usage.  For example batteries stored at 100% charge will degrade faster than batteries stored at 50% charge, this is why most consumer electronics devices arrive from the manufacturer with between 25% to 75% charge.

Lithium-ion batteries are consumable components, however in most modern computers, cell phones, and tablets these are not user serviceable components.  To help maintain the battery all modern computers and most consumer electronics will include battery charge and protection circuits.  These can be fairly simple, charging up the battery at preset rates depending on the charge level to help maintain the battery life, or complex software controlled charging that monitors battery temperature, voltage and current draw to maintain the fastest charging while maintaining the battery longevity.

Modern notebook computers can be left connected to the original power cable or a docking station with charging capability for extended periods, and do not benefit from regular discharge/recharge cycles.  Our docking stations with charging capability rely on USB Type-C Power Delivery to power and charge compatible computers.  USB Type-C Power Delivery is a negotiated charging protocol between the host computer and the docking station or USB Type-C power supply, this allows the computer to draw only the power it requires, and even select the best voltage level for powering the computer.  In combination with a computer's built-in battery charging controller the computer is capable of maintaining the battery's optimal state even when left connected to a power source for an extended period of time.

Legacy Laptop Batteries: NiCad and NiMH

Older laptops, from the 1990s and some early 2000s, as well as some consumer electronics, and most rechargeable AA or AAA battery replacements use Nickel-Cadmium (NiCad) or Nickel-Metal Hydride (NiMH) batteries.  These batteries are slower to charge and discharge than li-ion batteries, and require very simple charge controllers, and in some cases can even be trickle-charged ( very low-current continuous charging ) if desired.

These batteries generally don't have smart charging controllers and to prolong the life of the battery required "training" or fully discharging and recharging the battery every so often.  Many laptop manufacturers recommended fully charging and discharging a new laptop 2-3 times to train the battery, this is not necessary with modern laptops.

Conclusion

Modern notebook batteries are managed by the computer's built-in battery charging circuit, and require little to no user intervention to maintain optimal battery health.  It does not harm the battery to leave the computer connected to an external power supply, so long as the computer is being used regularly.  If the computer is to be stored for a prolonged period then discharging the battery to between 50-75% can help to maintain the battery life.

Batteries are consumable components and degrade over time, however modern notebook computers can extend the battery life generally to meet or exceed the life of the computer's other electronic components.

When the TBT4-UDX1 is connected to an electrical power source and powered on, there will be a small solid green power indicator light present on the front of the unit.

When the TBT4-UDX1 is connected to a compatible host computer, there will be a small solid blue host connection indicator light present on the front of the unit.
 

The TBT4-UDX1 can provide up to 96W of power to charge a compatible host computer.

The TBT4-UDX1 has two downstream Thunderbolt ports.  Each time a device is connected to one of these ports, the amount of power provided to the host computer is lowered by 15W.

For example, if there is one device connected to a downstream Thunderbolt port, the total amount of power provided to the host will be 81W.

If there are two devices connected to both downstream Thunderbolt ports, the total amount of power provided to the host will be 66W. 
 

The TBT4-UDX1 is a Thunderbolt 4 docking station based on the Intel Goshen Ridge chipset. The display output capabilities of the TBT4-UDX1 are ultimately determined by the display output capabilities of the host system.

Thunderbolt 4 host system:

When the TBT4-UDX1 is connected to a computer with a Thunderbolt 4 port, the maximum number of displays that can be connected to the docking station is two.  

The TBT4-UDX1 has a built-in HDMI video output port, and two downstream Thunderbolt ports.

We include in the box with the TBT4-UDX1 a Plugable USB Type-C to HDMI adapter that can be connected to one of the docking stations downstream Thunderbolt ports.  

The video outputs via the TBT4-UDX1 are provided on a ‘first come, first served’ basis.  To expand further, if the dock’s built-in HDMI video output is in use, you can connect one additional display via a USB Type-C to video adapter.

If there are two USB Type-C video adapters connected to the dock’s downstream Thunderbolt ports, then the HDMI video output will not function.

Thunderbolt 3 host system:

Manufacturers have discretion when designing their Thunderbolt 3 systems in regard to how many displays are supported via a single Thunderbolt 3 port.  Some Thunderbolt 3 systems support two displays, while other Thunderbolt 3 systems will only support one display.

The same ‘first come, first served’ process described previously within the ‘Thunderbolt 4 host system’ section will still apply if the host system supports two displays.

USB Type-C host system:

Host systems with only a USB Type-C port will be limited to a maximum of one display. This display can be connected to either the dock’s built-in HDMI video output port, or via the included USB Type-C to HDMI adapter. 
 

The maximum display resolution supported when using the TBT4-UDX1 is 3840x2160, and the maximum refresh rate supported is 60Hz.  

Resolutions higher than 3840x2160 and refresh rates higher than 60Hz are not supported. 
 

The TBT4-UDX1 has one full-size Secure Digital (SD) card reader slot located on the front of the unit.  The SD card slot supports the SD 4.0 specification, and the UHS-II standard. 

The SD card reader utilizes a ‘friction’ mechanism in order to retain the SD card.  To insert a SD card, simply insert the card into the slot until the card stops. The card will remain partially exposed when fully seated.  To remove the card, simply pull the card from the slot (note, please be sure to eject the card from within the host operating system when doing so). 
 

The TBT4-UDX1 has four USB Type-A ports, one is located on the front of the unit and three are located on the back of the unit.

Each USB Type-A port supports 10 Gbps data transfer rates.
 

The TBT4-UDX1 has a power button located on the front of the unit. When the unit is connected to an electrical power source, the dock will power on automatically.

The unit can be manually powered off by pressing the power button once. After the unit is manually powered off, it can be manually powered back on by pressing the power button once. 
 

The two slots located are the left-hand side of the TBT4-UDX1 are anchor points that can be used for physical security cables (i.e. Kensington locks).  

You can then connect many different types of Thunderbolt and USB-C devices to the two Thunderbolt/USB-C ports on the back of the dock.  The type of functionality provided by the two ports on the back of the dock is ultimately determined by the capabilities of the host computer.

To put that another way, if the host computer has Thunderbolt 4 technology built-in, then both ports on the back of the dock will function as Thunderbolt 4 ports.  

If the host computer has Thunderbolt 3 technology built-in, then both ports on the back of the dock will function as Thunderbolt 3 ports.

If the host computer has USB-C technology built-in, then both ports on the back of the dock will function as USB-C ports.
 

No, the TBT4-UDX1 can only be oriented horizontally.

The TBT4-UDX1 has a wired Ethernet network port based on the Realtek RTL8156B chipset.  The Ethernet port can support up to 2.5Gbps Ethernet when connected to compatible 2.5Gbps Ethernet network infrastructure (both the Ethernet switch and Ethernet cables in use must support 2.5Gbps operation).
